Biuged BGD 500 Digital Pull‑Off Adhesion Tester

The Biuged BGD 500 Digital Pull‑Off Adhesion Tester is a portable, hand‑operated instrument designed to measure the tensile force required to detach a coating from its substrate. Using hydraulic pressure and interchangeable dollies, it provides accurate, repeatable adhesion‑strength data for coatings, films, laminates, mortars, plastics, and metals. The digital LCD display ensures clear, direct reading of pull‑off pressure, making it suitable for laboratory, field, and production‑line testing. The tester evaluates the pull‑off strength of a coating by bonding a metal dolly to the coated surface using a high‑strength adhesive. Once cured, the instrument applies a steadily increasing tensile force perpendicular to the surface until the coating detaches or a specified limit is reached. The maximum pressure recorded represents the coating’s adhesion strength. This method identifies failure modes across the weakest plane in the system—dolly, adhesive, coating layers, or substrate.

Key Features

Standards‑Aligned Adhesion Testing

Supports internationally recognized pull‑off adhesion methods used in ASTM, ISO, and related standards. The BGD 500 is widely used for coatings, films, laminates, plastics, metals, concrete, and mortars.

Portable, Self‑Contained Design

A compact, lightweight body with a built‑in rechargeable lithium battery allows testing anywhere without external power. All tools required for testing are included.

Digital LCD Pressure Display

Hydraulic pressure is displayed digitally, providing clear, accurate readings of adhesion strength with 0.01 MPa resolution and ±1% full‑scale accuracy.

Interchangeable Dollies for Multiple Ranges

Four dolly sizes are available to match different testing resolutions and coating types:

• 20 mm (standard)

• 10 mm, 14 mm, 50 mm (optional)

This flexibility supports both high‑strength and low‑strength coatings.

Automatic Pull‑Off Control (BGD 500/S Variant)

The BGD 500/S version includes an electronically controlled hydraulic pump that applies smooth, continuous pull‑off pressure automatically, reducing operator influence and improving repeatability. It also stores maximum pressure, pull rate, test time, and dolly size.
